Description

Technical Field

[0001] The present invention relates to a method for painting an oil painting and an oil painting.

Background Art

[0002] For example, impressionist oil paintings, an artistic movement that originated in France, are often expressed with subdued colors without gloss on the surface of the oil painting. Generally, it is often considered that oil paintings are of such a form of expression.

[0003] On the other hand, there is also a desire to adopt a form of expression that gives a strong gloss to oil paintings. In Patent Document 1, for the purpose of obtaining a coating film having a luster, an oil paint containing a glass flake pigment in which flaky glass is coated with a metal or the like as an essential component has been proposed.

Summary of the Invention

Problems to be Solved by the Invention

[0005] By the way, when painting an oil painting using the oil paint of Patent Document 1, since this oil paint contains a glass flake pigment, it is assumed that a three-dimensional effect is brought to the surface of the oil painting.

[0006] However, from the viewpoint of demanding a gloss that gives a high reflectivity or a sense of transparency like a mirror surface or a water surface, if a three-dimensional effect is brought to the surface of the oil painting, it is assumed that the texture will be different from the desired gloss.

[0007] This invention has been made in view of the above circumstances, and aims to provide a method for painting oil paintings and an oil painting that can obtain a strong glossy finish. [Means for solving the problem]

[0008] To achieve the above objective, the present invention provides a method for painting with oil paints, comprising: a painting step of applying oil paints dissolved in an oily solvent to a support to be painted to paint an arbitrary picture and form a painting layer; a film removal step of removing a film formed on the surface of the painting layer formed in the painting step; and a thermosetting resin coating step of applying a thermosetting resin to the painting layer from which the film was removed in the film removal step to form a resin layer.

[0009] According to this method, by applying a thermosetting resin to form a resin layer, it is possible to create an oil painting that has a strong gloss that provides high reflectivity or transparency, like a mirror or a water surface, while suppressing glare.

[0010] The solvent used in this oil painting method is prepared by mixing turpentine oil and poppy oil, with a mixing ratio of 8 parts turpentine oil to 2 parts poppy oil. Furthermore, it is prepared by mixing turpentine oil and poppy oil and storing them at room temperature for a specified period of time.

[0011] The thermosetting resin used in this oil painting method is at least one of epoxy resin, urethane resin, or fiber-reinforced plastic.

[0012] In this oil painting method, the film removal process involves removing the film by applying an alcohol component to the surface of the painted layer.

[0013] To achieve the above objective, the oil painting according to the present invention is obtained by applying oil paint dissolved in an oily solvent to a support to be painted, drawing an arbitrary picture, removing the film formed on the surface of the painted layer, and then applying a thermosetting resin to the painted layer from which the film has been removed to form a resin layer. [Effects of the Invention]

[0014] According to this invention, it is possible to paint oil paintings that exhibit a strong gloss, resulting in high reflectivity or transparency similar to that of a mirror or a water surface. [Brief explanation of the drawing]

[0015] [Figure 1] This figure shows a schematic cross-sectional view illustrating the general structure of an oil painting according to an embodiment of the present invention. [Figure 2] This is a diagram illustrating the general configuration of the support 11 according to this embodiment. [Figure 3] Similarly, this is a flowchart illustrating the outline of the oil painting method according to this embodiment. [Figure 4] Similarly, this figure schematically illustrates the outline of the oil painting method according to this embodiment in cross-sectional view. [Figure 5] This figure shows an example of an oil painting according to an embodiment of the present invention. [Modes for carrying out the invention]

[0016] Next, an oil painting according to an embodiment of the present invention will be described based on Figures 1 to 5.

[0017] Figure 1 is a schematic cross-sectional diagram illustrating the general structure of the oil painting according to this embodiment. As shown in the figure, in this embodiment, the oil painting 10 is composed of a support 11, a drawing layer 12 laminated on the support 11, and a resin layer 13 laminated on the drawing layer 12.

[0018] The support 11 is an object on which oil paint is applied and any picture is drawn. Examples include what is generally called a "canvas," which is formed by attaching linen cloth to a rectangular wooden frame created by driving nails into it, or what is generally called a "panel," which is formed from board material. In this embodiment, a canvas is used.

[0019] Figure 2 is a diagram for explaining the schematic configuration of the support 11. As shown in the figure, in this embodiment, the support 11 as a canvas is, in this embodiment, made of two lightweight veneer boards 11-1, 11-1 having a thickness of about 5 mm and formed into an arbitrary shape (for example, an ellipse), an extruded foam polystyrene 11-2 made of polystyrene resin interposed between these veneer boards 11-1, 11-1, and linen (not shown).

[0020] In this embodiment, the support 11 is formed by applying an adhesive such as woodworking bond to both surfaces of the extruded foam polystyrene 11-2, and then pressing with a pressing tool such as a crimping machine in a state where both surfaces of the extruded foam polystyrene 11-2 are sandwiched between two veneer boards 11-1, 11-1.

[0021] The crimping by the pressing tool is maintained for about two days until the adhesive dries, and then the extruded foam polystyrene 11-2 is cut along the outer edges of the two veneer boards 11-1, 11-1 formed into an arbitrary shape, and the support 11 of an arbitrary shape is created.

[0022] At this time, it is preferable that a mounting member such as a heat sink is provided on the back surface of the support 11 so that the oil painting 10 can be hung on the wall.

[0023] Unlike the support of a general rectangular wooden frame that is nailed, the support 11 of this embodiment is created by crimping the lightweight veneer boards 11-1, 11-1 and the extruded foam polystyrene 11-2 through an adhesive without using nails as described above.

[0024] Therefore, its shape is not limited to a general rectangle for oil paintings, and it can be easily processed into a special shape such as an ellipse or a circle, which is not commonly used for oil paintings and is unfamiliar to them.

[0025] Furthermore, since the support 11 can be created without using nails that rust due to aging, it is expected that the durability of the oil painting 10 will also be improved.

[0026] In this embodiment, the extruded polystyrene foam 11-2 used in the support 11 is expected to be, for example, "Styrofoam" (registered trademark), which is used as an insulating material.

[0027] In this embodiment, the drawing layer 12 is formed by laminating it onto the support 11 when oil paint is applied to the support 11 and an arbitrary picture is drawn on it. Generally, when drawing a picture with oil paint, the oil paint is dissolved in a solvent made of a drying oil such as linseed oil or poppy oil before drawing.

[0028] In this embodiment, this solvent is prepared by blending turpentine oil and poppy oil.

[0029] When the oil paint dries and the drawing layer 12 is formed, a film is formed on the surface of the drawing layer 12 due to the oil content caused by the solvent. In the solvent, if the proportion of poppy oil is lowered and the proportion of turpentine oil is increased, the resulting film becomes thinner, but the brushstrokes of the oil paint are more easily preserved.

[0030] In this embodiment, from the viewpoint of making the formed film thin, it is preferable to set the mixing ratio of turpentine oil to poppy oil to 6-8 parts turpentine oil to 4-2 parts poppy oil, and in particular, it is preferable to set it to 8 parts turpentine oil to 2 parts poppy oil.

[0031] In this embodiment, the solvent is preferably prepared by blending turpentine oil and poppy oil and storing it at room temperature for an arbitrary period, for example, 1 to 2 days.

[0032] In this embodiment, the resin layer 13 is formed by laminating it onto the drawing layer 12 by applying a two-component thermosetting resin to the drawing layer 12.

[0033] When painting with oil paints, it is common practice to apply a protective varnish, such as alkyd resin, polyurethane resin, or natural resin, to the surface of the painting layer to protect it from deterioration over time, such as discoloration (yellowing) or cracking.

[0034] In the oil painting 10 of this embodiment, instead of these resins, a two-component thermosetting resin is applied to the surface of the drawing layer 12 to form a resin layer 13.

[0035] In this embodiment, the thermosetting resin is preferably at least one of epoxy resin, urethane resin, or fiber-reinforced plastic (FRP), and is particularly preferably epoxy resin.

[0036] Generally, thermosetting resins, especially epoxy resins, are materials often used in industrial fields such as ship hull coatings and building material coatings. Because they have the property of repelling water even with a small amount of oil, they are not commonly used in oil painting.

[0037] Next, a method for painting the oil painting 10 according to this embodiment will be described.

[0038] Figure 3 is a flowchart illustrating the general method for painting the oil painting 10. As shown in the figure, the method for painting the oil painting 10 according to this embodiment consists of a painting step S1, a film removal step S2, a thermosetting resin coating step S3, and a heating step S4.

[0039] Before performing the drawing process S1, first, turpentine oil and poppy oil are mixed together and, in this embodiment, stored at room temperature for 1 to 2 days to prepare the solvent in advance.

[0040] In this embodiment, the mixing ratio of turpentine oil to poppy oil is preferably in the range of 6-8 parts turpentine oil to 4-2 parts poppy oil, and in particular, a mixing ratio of 8 parts turpentine oil to 2 parts poppy oil is preferred.

[0041] Along with preparing the solvent, prepare a support 11 molded into any desired shape.

[0042] Next, in drawing step S1, oil paint is dissolved in a solvent and applied to the support 11 to draw a desired image. Once the oil paint dries, the drawing layer 12 is laminated and formed on the support 11.

[0043] Once the oil paint dries and the painting layer 12 is formed, a film is formed on the surface of the painting layer 12 due to the oil content caused by the solvent. In this embodiment, the solvent is prepared by increasing the ratio of turpentine oil to poppy oil, so a relatively thin film is formed.

[0044] Next, in the film removal step S2, the film formed on the surface of the drawing layer 12 formed in the drawing step S1 is removed. In this embodiment, the film is removed by applying an alcohol component to the surface of the drawing layer 12.

[0045] As described above, the film formed on the surface of the drawing layer 12 is relatively thin in this embodiment, and can therefore be easily and reliably removed, for example, by impregnating a cloth material with a low-concentration alcohol component and applying it.

[0046] In the film removal step S2, the film on the surface of the drawing layer 12 is removed, and then in the thermosetting resin coating step S3, a two-component thermosetting resin is applied to the surface of the drawing layer 12 to form a resin layer 13.

[0047] In this embodiment, the thermosetting resin is preferably an epoxy resin, but it may also be a urethane resin or a fiber-reinforced plastic.

[0048] Here, as mentioned above, thermosetting resins have the property of repelling water even with a small amount of oil. Therefore, if a thermosetting resin is applied to the surface of the drawing layer 12 without removing the film formed on the surface of the drawing layer 12, the thermosetting resin 13a will repel water from the surface of the drawing layer 12, as shown in Figure 4, and it will not be possible to form the resin layer 13.

[0049] Therefore, prior to the thermosetting resin coating step S3, it is necessary to remove the film from the surface of the drawing layer 12 in the film removal step S2. By removing the film, the thermosetting resin 13a can be applied to the surface of the drawing layer 12 without causing water repellency.

[0050] Incidentally, in this embodiment, the solvent is prepared with a higher ratio of turpentine oil to poppy oil. As mentioned above, when painting with such a solvent, the brushstrokes of the oil paint tend to remain visible.

[0051] In such cases, when the thermosetting resin is applied to the surface of the drawing layer 12 in the thermosetting resin coating step S3, the surface of the drawing layer 12 dissolves, and the brushstrokes of the oil paint also dissolve and disappear. Therefore, the texture of the oil painting 10 is improved.

[0052] Before the thermosetting resin applied to the surface of the drawing layer 12 hardens, i.e., during the hardening process, air bubbles may form in the applied thermosetting resin. In this case, the area where the air bubbles have formed is heated using a heating device such as a heat gun or burner to remove the air bubbles, and the heating process S4 shown in Figure 3 is performed.

[0053] By performing the drawing process S1, the film removal process S2, the thermosetting resin coating process S3, and the heating process S4, an oil painting 10 like the example shown in Figure 5 is completed.

[0054] As shown in the illustration, the oil painting 10, when coated with a thermosetting resin to form a resin layer, has its glare suppressed and exhibits a strong gloss that provides high reflectivity or transparency, similar to a mirror or water surface.

[0055] Furthermore, compared to cases where alkyd resins, polyurethane resins, or natural resins are applied to the surface of the drawing layer as a protective varnish, the resin layer formed by thermosetting resins is less prone to discoloration and cracking, thus extending its service life.

[0056] As described above, thermosetting resins are not considered to be commonly used materials in oil painting. However, since the use of thermosetting resins results in a strong gloss, giving the oil painting 10 a very distinctive appearance, it is thought that employing a process involving thermosetting resins in the painting method of the oil painting 10 would not be achievable even with ordinary creative abilities.

[0057] Furthermore, when applying the thermosetting resin to the drawing layer 12, it is necessary to remove the sebum formed on the surface of the drawing layer 12. From the viewpoint of facilitating and ensuring the removal of sebum, it is preferable that the sebum formed on the surface of the drawing layer 12 be thin.

[0058] In this embodiment, focusing on the fact that a film is formed by oils originating from the solvent, the solvent is prepared by increasing the ratio of turpentine oil to poppy oil, resulting in the formation of a relatively thin film.

[0059] Therefore, since sebum can be easily and reliably removed, the thermosetting resin can be applied to the drawing layer 12 in good condition.

[0060] Furthermore, if a thermosetting resin is applied to the painting layer 12, it is conceivable that the weight of the resin layer 13 may cause the oil painting 10 hanging on the wall to fall from the wall, or that its weight may make it difficult to transport. However, in this embodiment, since the support 11 of the oil painting 10 is made lightweight, the inconveniences of handling the oil painting 10, such as the oil painting 10 falling or difficulties in transporting it, are suppressed.

[0061] The present invention is not limited to the embodiments described above, and various modifications are possible without departing from the spirit of the invention.

[0062] In the above embodiment, the case in which the heating step S4 is performed following the thermosetting resin coating step S3 was described. However, if the bubbles generated in the thermosetting resin during the thermosetting resin coating step S3 are so minute that they are hardly noticeable, the heating step S4 may not be performed.
